Abstract

Blending polyvinyl alcohol (PVA) -Carboxy methyl cellulose (CMC) - Acrylamide (AA) membranes are prepared and crosslinked using succinic acid and investigated it as a polymer electrolyte membrane (PEM) in direct methanol fuel cell (DMFC). The membranes were prepared through the solution casting technique. The effect of different blend addition on physicochemical properties was studied. Scanning electron microscopy (SEM) was used to study the morphological structure, which indicated that no phase separation or cracks and good component compatibility. Chemical interaction between PVA, CMC, and AA was confirmed using Fourier transform infrared (FT-IR) in which the four characteristic absorption bands at 572, 1414, 3302 and 3411 cm-1 which confirm the presence of -NCO-, -COO-, -OH and -NH2, respectively. Furthermore, mechanical strength, water uptake, gel fraction, and ion exchange capacity (IEC) were determined as functions of varied membrane components. The results revealed that the addition of CMC and AA improves mechanical strength, IEC and protonic conductivity that reached 23.41 MPa, 0.11 mmol/g and 1×10-3 S/cm, respectively. Such results enhance the potential feasibility of PVA/CMC/AA hybrid polyelectrolytic membranes for DMFC application.
